Files that contain the .c00 file extension are created by the WinAce file archiving software. WinAce takes batches of files and compiles them into a single archive file. The archive can then be split into smaller volumes to allow for easier transmission of the file over the Internet and via email.
Each volume of a split file archive is given its own extension in sequence. The .c00 extension is usually given to the first volume of the split file archive.
In order to extract the contents of a split archive file, all of the volumes of the split archive must be present.

File.org aims to be the go-to resource for file type- and related software information. We spend countless hours researching various file formats and software that can open, convert, create or otherwise work with those files.
If you have additional information about the C00 file format or software that uses files with the C00 suffix, please do get in touch - we would love hearing from you.
